Specification of Letters ]Patent. P m mm NQWU 23 191mg Application filed January 31, 1916. Serial No. 75,257.

To all whom it may concern Be it known that I, FRANK E. SAECKER, a citizen of the United States, andresident of Appleton, in the county of Outagamie and State of Wisconsin, have invented certain new and useful Improvements in Wood- Barking Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.

The present invention relates to new and useful improvements in Wood barking mechanisms of the type embodied in Patent No. 1,043,608 granted to B. J. La Moine & J. P. Shafer November 5, 1912, and is more articularly directed to the provision 0 an improved means for holding a log in working relation to the cutting wheel of the machine. In the structure embodied in the said patent, a single roller is provided at the front of the knife wheel casing, for holding a log thereadjacent, and this arrangement presents a serious difficulty 'in that it is only adapted for holding logs of one general size, for if the roller be spaced a comparatively great distance from the casing, the bottoms of relatively small logs will rest on the bed between the roller and the casing and be not engaged thereby, while if the roller is'positioned adjacent the casing to operatively coact with relatively small logs, larger logs will have their bottoms restin outwardly of the roller with their peripherles spaced from the roller.

It is the object of the present invention to overcome this disadvantage in the present machine by providing log holding means which are operable in connection with logs which vary in size to a relatively great extent whereby the machine may accommott date all sizes of logs which would normally be encountered in operation.

It is further an object to provide such a holdin means to accommodate all sizes of logs w erein an additional gripping means at may be provided for logs of relatively great size to facilitate their rotative manipulation.

vantages in view, the invention resides more partlcularly 1n the novel combination, ar-

rangement and formation of parts more With the above and other objects and adthe machine in a plane at right angles to and including the axis of the knife wheel shaft, this view being similar to the View illustrated in Fi 5 of the said patent. Fig. 2 1s a horizonta sectional view on the line 2-2 of Fig. 1 showing the mountings for the holding rollers,

Referrlng now more particularly to the accompanying drawings, a portion of the general structure of the said previous patent is illustrated which includes the knife wheel 5 mounted on a shaft 6 and rotatable in a vertical casing 7 provided in its inner wall with the opening 8 permittin introduction of the peripheral portion of t e log therein. Spaced opposite the knife wheel casing is the frame or casing 9 which holds the slide member 10 to which is attached the weight 11, this slide member being controlled by theusual manually manipulated gear wheel 12 meshing with teeth thereon and having pivoted thereto the slotted link 13 and the yoke bar 14 carrying the sprocket wheel 15 around which is trained the toothed chain 16 which engages the upper portion of the log to rotate the same, the slide member and its respective cooperating parts providing in the usual manner for a swinging adjustment of the chain on its sprocket Wheel 17 carried by the knife casing, to adapt the chain for engagement with logs of greatly varying sizes. Disposed transversely between the casings 5 and 9 and connected therewith in spaced relation are the bracket bars 18 which support the usual conveyer 19 adjacent the casing 9, and which, adjacent the knife wheel casing 5, are provided with bearings 20 carrying the usual shaft 21 on which is mounted the holding roller sections 22, the shaft and sections be1n hereinafter generally termed the inner olding roller.

The foregoing is the structure disclosed in the patent and possesses the disadvantage of not being adapted for logs of a relatively great size, inasmuch as such logs would engage the bars 18 outwardly of the roller and hence would not be operated upon by said roller to hold the lower part of the log up against the knife wheel. To overcome this disadvantage, which in actual commercial practice has been found to very materially detract from the value of the machine, the present invention provides a shaft 23 similar to the inner roller shaft ltll 21 and journally carried by the bars 18 between the inner roller and the conveyer, this shaft carrying roller sections 2-1: similar to sections 22 .and this structure being hereinafter termed the outer roller member. The axis of the shaft 23 is disposed considerably below the axis of the shaft 21 and consequently the periphery of the outer v roller is disposed below the periphery of the same to slip therefrom.

' The shaft 21 of the inner roller member carries at one end a pulley 25, which in the usual construction of the machine is rotated by a belt 26and to provide for rotation of the outer member its shaft 23 also carries a. pulley 27,-Which may be rotated by an additional turn of the belt 26 or by any other desired means.

From theforegoing it will be observed that an exceedingly simple arrangement has been provided which materially increases the value of the machine embodied in the aforementioned patent in that it adapts the machine for the manipulation of logs of all the various sizes that would be encountered in ordinary practice.

Although a driving connection has been shown and described for both rollers, it will be obvious that a driving means for the outer roller is not essential in the operation of the machine, as the outer roller serves essentially as a means for holding the log from slipping from the inner roller inasmuch as the axis of the outer roller is disposed outwardly of the largest log that would be encountered under usual conditions.

I clainr:

In a wood barking machine the combine, tion with a knife wheel and adjustable means for rotatively engaging the upper portion of a. log to hold it against said wheel of a pair of rollers disposed below said means in parallel relation to form a bed for the log and having their axes in a plane inclined downwardly from the said wheel, and means for rotating said rollers.

In testimony that I claim the foregoing I have hereunto set my hand at Appleton, in the county of Outagamie and State of \Visconsin, in the presence of two witnesses.
